Specification of Letters Patent.

Patented Aug. 20, 190'?.

Application tiled September 11,1906. Serial llo. 334,142.

To all whom 'it may consom:

f Be it known that l, 'Persa GRANT BURNS, a citizen ofthe United States, residing at St. Louis, in the county of St. Louis and State el Missouri, have inventcd certain new and useful Improvements in Wood-Preserving Apparatus, for which the following is a specification.

This invention relates to wood preecr ration und more particularly to apparatus for treating timber with a. liquid preservative, and the object is to provide apparatus by which railway cross-tics and other timbers can be transported te a vat or tank containing a liquid preservative and submerged in the liquid and made to traverse, making a circuit under the surace of the liquid preservative for a considerable period of time and then transported toV suitable places to be dumped on cars. Provision is made for heating the liquid in the tank or vat and provision is made for stirring thc liquid in the tank or vat. i

One of the obiects of this invention is to prepare or provide a portable wood preserving plant which can be transported from one lumber yard to another and transported any reasonable distance. i

Gne of the advantages of this invention is that the handling oi the ties or other timber from the time they are placed on the tramways until they have been treated with the liquid preservative until they are ready to be dumped on cars again is accomplished entirely by mechanical means, the ties or timber never stopping from the time they are placed on the tramways until they have made the circuit through the vat or tank and have moved to the cars on which they are to be dumped.

Other objects and advantages .will be fully understood from the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which forms part of this application and specification.

Figure 1 is a broken plan view on a small scale otV the wood preserving plant. Fig, 2 is a plan detail vic-u1 of the rollers for turning the curves in the tramways. Fig. 3 is a side elevation of a portable wustl preserving'- plant. Fig. 4 is a broken plan view of the vat on an enlarged scale. Fig. 5 is a-broken plan viewillustrating the apparatus for stirring the liquid in the vat. Fig. 6 is broken vertical section of the tank or vat illustrating the stirring mechanism. Fig. 7 is a vertical section of the tank or vat, illustrating the meansl for heating the liquid in the tank or vat, and the means for transporting the timber into `and out of the tank or vat. Fig. 8 is a broken detail view, illustrating the means for starting the timber into the tank or vat. Fig. 9 is a plan view of the receivingtable which delivers the timber to the conveying devices shown in Fig. 8. Figs 10 is a side elevation of the table shown in Fig. 9, Fig. 10 illustratflig. 11 is a vertical secup of the-table shown insign 9 and 1o. rig, is is broken detail view of the discharging mechanism, being a side elevation. Fig. '13 is a plan view el the discharging rollers. Fig. 14. is a detail view illustrating the manner el mounting the rollers which receive the timber from the vat conveyor chai-n. Fig. l5 is plan view of a section of a tramway. Fig. 1li is a side elevation, illustrating the manner of driving the rollers o the tramway. Fig. 17 is a side elevation of the plant as shown in Fig. l, the vat or tank.

Similar characters of reference are used to indicate the same parts-throughout tho several views.

The invention herein described may consist of o. portable plant for treating wood, as shown more particularly in Fig. 3 o the drawings.

ln Fig. 1 is shown a plan of the entire plant as nearly complete as can be shown on one shectiof drawings.

A indicates the tank or vat in which is placed the preserving liquid.

B represents a car load of timber to be treated.

G represents a. tramway for conveying the timber from the car B to the vat A.

Direpres'ents the receiving apparatus or table on which the timber is received from the tramway G to be started into the vat.

E represents the discharge carrier rollers which receive the timber after it has been treated in the vat and starts the timber on the tramway F which delivers the same to a car G.

The tramways C and F `are constructed of side trarne pieces l with driven toothed rollers 2 and idlers 3 1eurnaled in the frame pieces 1. The toothed rollers 2 are driven by sprocket wheels 4 and chains 5 and El, and the sprocket chains 5 ond (3 may be driven by any suitable power. Both tramways are curved towards the vat A. The tramway/sare provided at the curved portions with driven rollers. See Fig. 2. The rollers 7 are driven rollers and are journaled in the curved ,ironie pieces 8. The rollers 'i' are provided with pulley wheels 9 which are double groovcd pulleys and also with single grooved pulleys 11 and 12. The pulley l1 is mounted on the shaft o the last driven pulley in tramway 7. The rollers 7 are all driven by the power derived from the last toothed roller 2 by means of the pulleys 11 and 12, and by the cables 10. Idlers 13 hold the cables 10 in operative relation. From the rollers the timber is received on a table D. The rollers turn the timber so that it is in position to enter the vat cross-wise. The table D is provided with n rocking frame 14 which is journalcd irl-bearings l5. The bearings l5 are attached to suitable supporting traine pieces lil. ldlors 17 are journaled in the rocking frame i4 only, the outer ends oi these conveyor rollers being free or without bearings. Counter weights 18 are attached to the rocking traine 14 vfor holding the frame and the rollers in their normal position to receive the timber kom the turn-table rollers Fig. 18 is a vertical cross-section of 7. The timber may be shoved on the rollers 17 by hand. Win-n the timber is received ou the rollers 17, it in in position to bc dclivercd to the vat. The timber is tnken from the rollers i7 by mcuns of dumping.r rollers 19. 'l`he timber lyinlhr on the rollers 17, the weights i8 are raised and the. rollers` vI7 will be tilted down :so the timber will bc received on tluA rollers i9 and carried to traveling sprocket chnius 20. 'll frame pieces 2l in which the rollersl .lilnrejourniiled are inclined aoshown so that the timber will descend by gravity* to the chains 20.

It is apparent that the weights i8 may be varied in size :ind adjusted on the beams 22 so that an operator can easily tilt or rock the lrame. The sprocket chains 20 are driven by sprocket wheels 23. When the timber reaches the chains 20 it is carried lrind dumped on the tracks` 2G. In Figs. 10 and ll the upright frame pieces 25 are broken away for convenience in grouping the drawings. A The vat or tank A may be of any suitable shape. The vat shown is a rectangular trougl1like structure which may be shallow at the receiving end. The timber is received on tracks 26 mounted ou the bottom of the vat. The timber is moved along in the vat by two sprocket chains 27 which have outwardly projecting teeth 28 which project close enough to the tracks 26 to move the timber. The pieces of timber will probably float up next to the sprocket chains 27. These chains run uuder the surface of the liquid preservative. The tracks 2G extend the entire length of the wat below the sprocket chain und curvo upward and back through the vat above the Sprocket chains 27, ns clearly shown in Fig. 7. The tracks are submerged in the liquid except at the receiving and discharge ends. The sprocket chains 27 are driven by sprocket wheels 2l). The timber will rise up at the end H ofthe vat and follow the tracks 26, but the teeth of the sprocket chain would force the timber up to follow the tracks. Above the sprocket chains, the timber would probably float up against the tracks 26 instead of resting on the sprocket chains. will force the timber along. The time of travel frozn the receiving end of the vat through the vat and brick to the discharge may behind@ in any desired length. The sprocket wheel 29 nt the receiving end of the vat may be driven by a pulley 30 mounted on the shaft 32 With the sprocket wheels 2i) and by a belt 31 which is driven by the engine 33.

The sprocket chains 27 dump the timber on discharge rollers shown in detail in Figs. 12 to 14 inclusive. The timber is irst dumped on rollers 34 which are journaled in zin inclined frame 35, the rollers 34 being transverse the vat. The rollers 34 may be culled the dumping rollers. The rollers :i4 deliver thetimber to discharge rollers 36 and 37. 'lhe rollers 37 may be driven by pulleys 38 :uid belts 3!) which nre d.ven from the rollers 7 of thedischargo turntable. The, rollers 36 and 37 deliver the timber to the turn-table rollers 7 and the rollersl 7 deliver the timber to tho tramway l".

Menus :ire provided for heating the liquid in the vat A by stciun, vut. i Ono loyer llll ol the. circulating,r pipe is arranged near the bottom ol the trink. (lue lnycr 41 is horizontoll)r arranged bel weon the sides of Ille sprocket chains 27. And one lnyor 42 in nrriinged near the top of the trink, but is disposed beneath the surface of the liquid In either case the teeth of the sprocket chains I Steam pipes crculzite horizontally in the preservative. The pipe is of ordinary construction und may be connected to a boiler to carry steam from the boiler. lt is apparent that hot nir or n hot liquid could be used for hentinur the pipes. 'lbese pipes run buck and forth from side to Hidedn the 'vnt so that the liquid preservative will be hcnted at sill ports ol the vnl..

Means :ire provided for stirring llie lirpiid in the vut. Rotary Mirrors 43 nre mounted on upsrmiding;` simile or spindles which are mounted on ilu boltom ol the ini. These stirrcrs -ire driven by bevel gearing. -om geur wheel -14 heinkl rigid wi th the rilil'rem` i3 rind the copcnitim,r gem' wheel l5 being mounted ou the nhui't y46. Bearings -17 for the shaft Alli :ire mounted on the bottom of the vat A. 'lhe shalt iti projects out of the vat through n stnllini;r box 52 and n geur wheel 48 is mounted thereon. Geur wheel fl is driven by n gear wheel 49. A shaft 50 drives the geur wheel Alf) und thisl shaft is provided with n pulley 5l by which the shalt is driven.

The plant muy be a portable plant with the vat A mounted on n flut car, as shown in Fig. 3, or the plant muy be stationery, as illustrated in Fig. l?. The cnginc lll furnishes power for driving the rollers of the trmnways C and F. A band 53 driven by the engine 33 drives n sli-nit 54 through the large pulley 5.5. A band 56 driven from shnft 54 drives the pulley 57. A bend 58 driven from the shuit 54 driies :i pulley 5ft Pulley 5i! drivesy .shuit lid` which shoft furnishes power for drivingr the rollers oi irmnwny C and n bond ll trans-- mits power' for driving rollers 7 oi' the turntable. The band 5G drives n slnift G2 which furnishes power for drivintr the rollenA of trmnwriy l". A band G3 transmits power for driving the rollers of the discharge turntable.
